METHOD AND DEVICE FOR HYGIENIC COLLECTION AND COLLECTION OF ANIMAL BLOOD

The invention relates to a method and an apparatus for the hygienic removal and collection of animal blood, especially from pigs, cattle and sheep, with which Process the nutritional blood with Safety can be separated from the withdrawn animal blood, and what method and device in addition to one maximum blood withdrawal from the animals a hygienic and infection-free withdrawal of what is used for nutritional purposes Blood backs up.

The animal blood is a raw material that contains egg white in large quantities / the pig blood 18.5 # / and many recoverable, has extremely valuable components from a nutritional and biological point of view.

The extraction of animal blood takes place in the first period of slaughter in an area at risk of infection. In many countries it is a requirement to control the animal blood from the point of view of consumption and to ensure the identifiability between the carcass and the cut parts up to the last control station. Such regulations are in force in Hungary and also in the FRG. The regulations applicable in the latter country are ^{summarized in the magazine "Fleischwirtschaft 11} / 10.10.1981/, pages 1460-1464 / von Grätz.

With conventional blood sampling, the pig is roughly in the middle of the sting near the lower chin stabbed the lower chin. The prick cuts the main artery and lets the blood flow freely flow out of the animal's body. If the blood is processed further, so the animal is not pricked with a conventional kettle, but with a hollow knife and on the A hose is attached to the end of the knife, through which the outflowing blood is taken up into a jug. In the jug was previously put a coagulant. the The jug is kept at the blood collection point until the decision of vet.-med. Department arrives. As the carcass are not designated on the occasion of the engraving, but only later, the identification is not certain and the risk of infection is very high.

A much more modern method is the ALFA-LAVAL-VAMPIRE System in which the coagulant is introduced into the hollow knife, the blood is sucked off with a vacuum, and Washing and disinfecting liquid can be introduced into part of the system. Preventing the spread the infection, washing and disinfecting the hollow knife

and the identification are not resolved. Identification is based on the fact that the animals are in the order of the stitch on the slaughter line or on the last vet.-med. Arrive office.

Before the scalding and depilation, however, the animals can mix, the sequence can change and in this case the body of the animal cannot be identified with the blood. Another disadvantage of the system is that the blood of many animals can be lost before the vet.-med. Department is collected in a container, so that because of a single sick animal, the blood of many hundreds of animals is confiscated. Another disadvantage is that the blood is kept refrigerated, which means that it is difficult to separate the blood because the optimal temperature for separation is 3CMK) ⁰ C. Another disadvantage is that the knife used is a multi-edged knife that can be dismantled, which on the one hand leaves a large wound and on the other hand is difficult to clean because of the many surfaces. In this system, the blood drawn for nutritional purposes is 2.2-2.5% of the weight of the animal.

The BEMEG industrial planning device means one Development. This device consists of a carousel, which is provided with twelve, hose-equipped knives is. The carousel moves together with the pigs moving on a circular path, the blood passes through the knife stuck in the pig into a container that holds the blood of 4-0 animals, where it makes the decision the vet.-med. Office is waiting. With this device, the knife and hose are washed, but with an unfavorable degree of efficiency. The disadvantage of this solution is that the identification of the carcass and the blood is not solved, since this method is also based on adherence to the sequence. The risk factor of the procedure is also great, because of an objected animal that

Blood from 40! Animals is confiscated. The knife is that Knife of the VAMPIR system similar, so this too Knife is unfavorable. The amount of blood drawn corresponds to the amount of blood obtained with the VAMPIR system identical.

The Swiss Pinna RINEKER offers a better one Solution used in Hungary. With this method, washing the knife is identical to the BEMEG system. The risk factor is small, as only the blood of 5 animals flows into the same container. Its disadvantage is that the blood cooled before separation and the coagulant with a Pump is pressed into the knife, which is disadvantageous from the standpoint of clogging. Identification is also not solved here and is very costly. The knife can be dismantled, so it is difficult to disinfect. The removed The amount of blood cannot be greater than 2.5 #.

Of all known devices, the device from the Danish company NUTRIDAN is the most modern. The identification of the body and the blood is carried out by mechanical assembly with the help of elevated carriages, so the scalding and depilation of the animals in a vertical position is a condition of the applicability of the device. This device is only used in a very few places. Its disadvantage is that due to the large capacity, the blood is taken with two knives at the same time, which means problems when confiscating at the group borders, because it is not possible to determine in which group the blood of the confiscated animal is. Another disadvantage is that the risk factor is high, since the blood of 50 animals is collected in one container. Another disadvantage is that the knife can be dismantled. The amount of blood drawn is between 2.5 2.8 %.

The disadvantages of the known solutions are alleviated by the device according to the invention and by the

mass procedures eliminated. This device and this Process enable by applying a secure Identification method, with a smaller risk factor, the hygienic collection of a larger amount of animal blood for nutritional purposes with the help of a suitably trained Knife, whereby the invention by collecting the extracted blood at the original temperature promotes the separation of the stored blood.

The object of the invention is, above all, to implement hygienic blood sampling on a large scale Amount for nutritional purposes with the necessary devices, controls and mechanical methods. Besides that The task is also the appropriate solution to the collection of the confiscated blood that cannot be used for nutritional purposes the invention.

The invention ensures the correct identification of the carcass and the blood with the exclusion of mixing. It achieves perfect washing and disinfection, with every component that comes into contact with the blood being washed and disinfected before it is used again. In this way, the invention eliminates the spread of the infection of the animal bodies or of the collected blood. The invention collects the blood of the animals in an optimal amount and in an appropriate grouping, whereby the risk factor is low and the economy is high. The blood used for nutritional purposes leaves the blood collection container through a separate line and flows into the reservoir. This blood passes to a suitably high temperature / 32-34- ⁰ C / i _n the memory and is only cooled when it is not separated, or after the separation. By using an increased vacuum, the invention eliminates foaming of the blood. The closed system, the appropriately designed components and units prevent blood stasis and facilitate washing and disinfection of the

The invention ensures a maximum, advantageously 3.7 # -e blood withdrawal, which on the one hand the consumer gets more raw material, on the other hand the risk of spoilage of the bled animal body is reduced, because the most perishable substance that blood has left the body in the greatest possible amount. By means of control through the last vet.-med. Service agency realizes the invention with certainty the (separation of edible blood. The invention enables the contraction of different indexes / e.g. Trichinella, group number, blood sample number, etc./, which can save manpower.

With the aid of the device according to the invention and the method according to the invention, blood sampling and the collection of blood from animals of different types, sex and age can be carried out much more advantageously than before, according to the hygienic regulations of the developed countries, namely in such a way that from the entire blood stock of healthy animals 90 % can be used for nutritional purposes and only $ 10> is left for industrial purposes. The invention ensures that the blood unsuitable for nutritional purposes or the blood of suspicious animals reaches 100 # in the industrial blood collection system. :

The technical effect of the invention includes - in terms of the main process of the slaughterhouse - the operations from driving into the conventional stunning state to the rebleeding station and from the last one vet.-med. Office up to the switch that leads to the suspicious section of the railway.

The invention includes the devices for serial numbering of the carcass, for sterile tapping, for the blood collection process on the slaughter line Collecting, checking, separating and transporting the

The inventive method is in the the following examples.

Example 1.

On the pig slaughter line shown in FIG from a capacity of at most 100 pieces / hour, the pace of arrival of the pigs, to avoid them an accumulation caused by the conveyor's pusher plates given signals, which light signals at the stunning point ensure a regular stunning. After the rear feet of the pigs have been provided with noose chains, the pigs are hung up by their rear feet. arrive at the dosing point on an elevated train.

There are the hung up, waiting pigs, according to a signal given by a central control unit, advantageously with the help of a semi-automatic tool provided with a serial number, afterwards the puncture point on the lower chin of the pigs is appropriately designed Brush disinfected.

Then the disinfected lower chin is transported to the blood collection point at a suitable rate Pig the stabbing part of a hollow knife that was previously washed and disinfected from the inside and outside stabbed that the pig's blood exclusively through the hollow knife and through the hose connected to it into the next one on the carousel, previously washed and disinfected collecting container should flow. The blood arrives in a closed one System, exclusively with previously washed and disinfected agents / hollow knife, hose, container / in contact coming into the carousel-like arranged and rotated containers.

The blood withdrawal is promoted by a known vacuum, whereby the clotting of the blood by means of the addition of Coagulant to the spilled blood is prevented.

«IW tf W

The bleeding of the pig is triggered by a sound signal indicated, whereupon the hollow knife is taken out / one end, the stabbing end, out of the wound, the other End, the end of the hose, out of the container /, and then into the Washing and disinfecting device is placed in it Pig is by a ^ onvejor in the rebleeding device transported. Then it is done with another, washed and disinfected hollow knife from the When the pig arrives at the blood sampling point, blood is taken in the manner described above and the blood is poured into the Collection container let in. !

In the example there are ten sumps on the perimeter des K & russels are generally arranged at the same distance from each other and the blood of ten successive pigs is admitted into each container. The serial number of the Taking blood from the incoming pig is expedient indicated on a scoreboard.

If a light or sound signal advantageously shows that the blood of the tenth pig has also flowed into the collecting container, the carousel with the blood-filled container, which closes automatically and expediently, rotates by oi-.r. _: Position next / in the example with an angle of 36 ^U / and the next, washed, disinfected, empty container is rotated into the blood sampling position A. The filling of this container with the blood of the ten pigs following in the row is carried out in a similar manner to that described above.

The twisting of the Karueeels or container:? Dt the further below the bled Schweinekorpor · on the Bchlacbtlinie so coordinated, that if after the blood of the blood-filled container, in accordance with the example of four standby positions B, 0, D, E, the Performs fifth twisting step, that is, in relation to each other

to the blood sampling point A rotated by 180 °, in this sixth emptying position F of the container for edible Blood from the ten pigs whose blood this container contains, has already arrived at the veterinary medical service are. The vet.-med. Service department controls this fact in such a way that the display board present there the Serial number of the at the vet.-med. Service station showing incoming pigs one after the other.

If the vet.-med. The office qualifies the blood of all ten pigs in the container for edible blood located in the emptying position F as suitable for nutritional purposes, it sends a signal through the central control unit to empty the blood in the container into the storage system or processing system for the edible blood. The edible blood is discharged - in the interest of the advantageous implementation of the separation of blood plasma and whole blood - with the help of a special pump at a high temperature / 32-34 ⁰ G /. If only one of the ten pigs is suspect or has to be confiscated from a nutritional point of view, if not all ten pigs arrive at the vet.-med office / if one fell off the convoy on the way, then vet.-med forbids. Department empties the blood in the container into the system for edible blood, and the container filled with blood is moved into the seventh position, expediently into the waiting position G and even further into the emptying position of the junk blood H. According to the example, this position is the eighth position, which is rotated from the blood withdrawal position A by an angle of 252 °.

In this position, according to the example, he is The container is set to empty, whether it is empty, i.e. the edible blood has already been emptied, or filled with confiscated blood arrives.

In the following ninth position I, that of the blood

removal position A rotated by an angle of 282 ° the container arrives empty. Here is the Containers washed and disinfected.

The container progresses to the tenth position J, that of the blood withdrawal position A by one Twisted angle of 324 ° is where the cleaning fluid is is emptied. In this position J the container is opened by connecting the disinfected hoses / hollow knife hose, Vacuum hose, drainage hose / prepared for the following cycle.

The container then rotates into the first blood collection position A, where in the manner described, under perfectly hygienic conditions, with disinfected Means in a closed system, the blood withdrawal is repeated, or the blood collection cycle and the separation of the blood in ten positions by rotating the carousel through 360 °.

The vet.-med. Service identified on the basis of the presence in the pig's ear and upon arrival of the pigs on the display board reporting serial numbers that the content of the emptying position F is located The container-forming blood from ten pigs with the associated, the controlled blood-donating carcasses.

If there is a suspicious pig or a pig to be confiscated in the group of ten pigs, forbidden the vet.-med. Department emptying the one in the emptying position F via the control line Into the edible blood system, and the defective carcass is placed on the suspicious section of the track guided.

If the animal is between the blood collection point and the vet.-med. Confused office when falling, or If the animal is not hung back in its original position, the number indicator will be displayed at the service station moved further, but the blood of this group can in this

closed system, under sterile conditions, the discharge of the edible blood from the pig's body to the separator 11b and separates from that with certainty removed blood the confiscated blood and leads it into the collecting container 12b.

FIGS. 3 and 4 show the structural design of the periodically rotating carousel 8 with the carousel on it attached - in the example see pieces - containers 10 to collect the blood. The containers 10 are expedient made of stainless, acid-proof steel, conical top and bottom, standing cylindrical containers, which firmly withstand the external pressure when an internal vacuum is formed. The inner and outer surface the container 10 is advantageously polished completely smooth.

The stopper 32 of the hose can be attached to the tubular mouthpiece 16 located on the upper part of the container 10 39 of the hollow knife 9 is connected with the aid of a pipe socket 32a will. Through these components, the blood flows from the pig's wound into the container 10. Dem Mouthpiece 16 closes on the side a connection piece 17 for the vacuum and a connection piece 18 for the Coagulant. A vacuum line can be quickly and easily attached to the connection piece 17 with a releasable bond 13a and a hose 18a can also be detachably connected to the connection piece 18 / FIG. 7 /.

The vacuum accelerates the outflow of blood from the animal's body and promotes the dosing of the coagulant. Furthermore, in that the vacuum the meat of the animal to the up to the flange 37 ia the Sucking hollow knives pierced under the pig's chin, secures this meat, which adheres elastically to the knife the flow of blood, hermetically sealed from the outer space, through the sterile hollow knife 9 and through

the hose 39 into the disinfected container 10.

For emptying the blood according to the hygienic requirements, as well as for draining the washing liquid a closing member 19 is connected to the lower conical end of the container IO. This closing organ 19 is a piece of hose that is closed in the basic position with the aid of two cylindrical closing springs 24 and is held in the closed position, so that until the actuator, i.e. the pneumatic cylinder 25 or expediently the control member 26, by pressing the pin 27, the closing member 19 against the force of the Closing spring 24 by compressing the closing spring 24 does not open the blood or the washing liquid cannot flow out of the container IO. The carousel 8 is around the fixed shaft 20 with the help of a progressing device, in the example with a Maltese cross 21 / Fig. 5, 6 / i rotated periodically. The progress device and the whole inner space is covered with a hermetic envelope 23 made of stainless steel.

From Figures 2 and 4 it can be seen that, according to the example, in the course of progression, each one on the carousel 8 moving container 10 into the letter A to J designated positions arrives. In position A, the. connected to the hollow knife 9 Tube 39, the blood obtained from the stung animal into the previously washed and disinfected container 10 introduced. During the stay of the blood containing Container 10 in the waiting positions B to F takes as much time as the time in each container the blood giving ten pigs from the stitch point 5 to the vet.-med. Department q arrive. In the Emptying position F is the container 10 - depending on the instruction of the vet.-med. Department q - with help of the actuating element, i.e. the pneumatic cylinder 25 and the closing element 19, or containing the blood kept closed. After the waiting position G, in the emptying position H of the confiscated blood, the closing organ becomes 19 by means of the pin 27 of the control member 26, which is a pneumatic cylinder or in the example a organ provided with a compulsory path can be opened. After the washing and disinfecting position I and in the drip position J the control member 26 holds the closing member 19 open. In position J the tubes of the hollow knife, the vacuum and Entrinnungsmittelelleitung connected to the ßehalter 10.

After completion of the rotation of the carousel 8 by 360 ° reaches the next row, washed and disinfected container 10 with closed closing member 19 in the blood withdrawal position A, the filling of this container

begins with blood and the container is then placed in the already described way moved on.

The pneumatic cylinder 25, locked with the limit switches, and the control element 26 are fixed in place Shaft 20 attached.

In Fig. 7, the hollow knife provided with hose 39 is 9 shows which knife at least two are necessary so that they can be changed or alternated for each animal can be washed and disinfected. The hollow knife 9 is through the tubular handle 38 with the Hose 39 connected. The hose 39 can with the stopper

The device according to the invention works as follows:

On a slaughter line with a capacity of 100 pieces / hour equipped with a known control system is, the ear of the first hematopoietic pig in the waiting dispenser 4 / Fig. 2 / useful with a four-digit number Number marked. The first two digits of the four-digit number advantageously show how much the Has twisted the carousel, the third digit shows which container the pig's blood is in, the fourth Numeral shows which place the marked pig occupies in the group of ten animals. This serial number will also shown on the display panel 15.

After disinfecting the place of the sting on the Under the pig's chin, the pig is transported to the stitching point 5, where the carousel 8 and the previously washed, disinfected, empty containers that are coming their turn await the animal.

After the piercing part of the hollow knife 9 has been pierced into the pig up to the flange 37, the vacuum extending up to this piercing part sucks the meat of the animal onto the hollow knife 9 and thereby ensures a hermetic seal, and on the other hand the vacuum accelerates the inflow of the through suction blood in the container 10. After bleeding of the S _c hweines is the hollow knife 9, taken on light or sound signal, from the wound, the stopper 32 is disengaged from the mouthpiece 16 and another sterile hollow knife 9 ', a plug 32 and a Pipe socket 32a is connected to the mouthpiece of the container 10. In the meantime, instead of the bled pig transported further by the convoy, a new pig with a serial number arrives, from which pig the blood is taken in the manner described above.

After the blood of ten pigs has been admitted into the container 10 located in the blood withdrawal position A

was, except for the plug 32 and the pipe socket 32a also detached the vacuum line 13a and the hose 18a from the blood-filled container 10 and the carousel 8 is conveniently to a sound and / or light signal with the help of the Maltese cross 21 to an angle of 36 ° im Turned clockwise. As a result, the container 10 filled with blood moves from the blood withdrawal position A into the waiting position B, with a new, empty, disinfected container arriving at the blood sampling position A, which is filled with the blood of ten pigs in the manner already described.

The containers 10 filled with blood are driven by the carousel 8 in a cycle that corresponds to the duration of the blood withdrawal Entüricht, moved through an angle of 36. The containers 10 filled with blood wait in the waiting positions B to E until they have bled out in a container 10 each ten pig bodies at the vet.-med. Department q arrive where the serial number of these pigs is on the display board 15 appears and the vet.-med. Department q at the same time controls these pigs from the point of view of suitability for nutritional purposes. Simultaneously upon completion of this control, the container 10 containing the blood of these ten pigs is in the Emptying position F-for the edible blood. If after identification the ten carcasses with the blood in the latter container 10 - due to the an.der display panel 15 appearing serial numbers - the veterinary medical service q the ten carcasses as veterinarian flawless and thus the blood present in the container 10 in the emptying position F is suitable for nutritional purposes qualified, gives it through the central control unit to the actuator controlling the closing element 19, e.g. the _ pneumatic cylinder 25 instruction to open the closing element 19 and thereby for emptying the blood in the container through the insulated line 11 into the
